Welcome to our survey!
Hi! We are a research team of George Washington University. This survey will ask you simple questions regarding your purchase preference for used cars.
This survey will take about 10 minutes to complete. It can be stopped and picked up at any time. Your personal information will be kept private and won’t be shared with anyone else. The survey is subdivided in five sub-sections:
Current vehicle information
Future vehicle information
Choice Questions
Knowledge of electric vehicles
Demographic Information
We greatly appreciate your participation!
Consent
Informed Consent for Participation in a Research Study
You are invited to participate in a research study directed by Dr. John Paul Helveston of the Department of Engineering Management and Systems Engineering at George Washington University (GWU) and funded by the Department of Energy. Participation is entirely voluntary and you may obtain further information regarding this study by contacting us at gwuvehiclegroup7@gmail.com .
The purpose of this study is to identify the preferences and needs of car ownership in different communities. If you choose to participate in this study, you will be asked to answer an online survey about vehicle ownership and preference. The total amount of time you will spend on this study is 10 minutes. You may refuse to answer any of the questions and stop participating at any time.
Benefits : The most important reason why someone would like to participate in this study is that they can share their vehicle usage needs and help inform policies that decide incentives on EV ownership. You will not benefit directly from your participation in the study. However, the benefits to science and humankind that might result from this study include implementing electric vehicle subsidy policies that are more in tune with people’s requirements.
Concerns/Risks : You may not choose to volunteer for this study if you do not want to share information about your vehicle usage. Possible risks or discomforts you could experience during this study include: - Although very unlikely, there is a risk of email address information being compromised if it is shared and in case our systems are compromised. - Psychological stress could be caused by the time and effort spent answering the survey.
Confidentiality : Every effort will be made to keep your information confidential. However, this cannot be guaranteed. The data will be stored in a secured online database which only the PI and student researcher can access. If the results of this research study are reported in journals or at scientific meetings, the people who participated in this study will not be named or identified.
Additional Information : The Office of Human Research of George Washington University, at telephone number (202) 994-2715, can provide further information about your rights as a research participant.Your willingness to participate in this research study is implied if you proceed.
Participation to this survey is voluntary. To take a part in this survey, you must:
- Be at least 18 years old.
- Authorize us to analyze the data exclusively for research purposes.
By clicking on “I Agree”, you confirm that you have reviewed and understood the information provided in the welcome page and this consent page, and agree to participate in the “Car Ownership Survey”.
This study is about the purchase of your next vehicle.

Educational Page
Great Work! Now that you have shared a bit about yourself, we’d like you to consider a scenario in which you can choose a car from a set of cars with different attributes.
Let’s learn about the attributes.
| Types of Powertrain | Definition |
|---|---|
| Gasoline | Gasoline vehicles use an internal combustion engine (ICE) that burns gasoline (petrol) to create power. |
| Hybrid (HEVs) | HEVs take net propulsion energy from gasoline but utilize a small battery pack and electric motor to improve fuel efficiency, mostly through regenerative braking, engine downsizing, engine shutoff at idle, and power management. |
| Plug-in Hybrid (PHEVs) | PHEVs are similar to HEVs, except they typically have a larger battery pack that can be charged by plugging into an electrical outlet. |
| Electric (BEV) | BEVs run purely on electricity and do not use gasoline |
| Types of Powertrain | Definition |
|---|---|
| Gasoline | A conventional gasoline vehicle uses only gasoline. |
| Hybrid (HEVs) | A hybrid vehicle uses a small battery to reduce fuel use but cannot be plugged in to rechage as it uses only gasoline. |
| Plug-in Hybrid (PHEVs) | A plug-in hybrid vehicle has a battery which can be plugged in recharge and can also use gasoline. |
| Electric (BEVs) | A battery electric vehicle must be plugged in to recharge its battery - it never uses gasoline. |
| Attribute | Description |
|---|---|
| Powertrain | Does the vehicle run on gas or Electricity? |
| Range | How many miles in a full tank/ fully charged battery |
| Price | What is the price of the vehicle |
| Model Year | Model/Manufacturing year is the actual year the vehicle was built |
| Mileage | The number of miles vehicle has travelled while in operation |
| Operating Cost (Equivalent Gasoline Fuel Efficiency) | Operating cost of the vehicle |
